Southwest winds are pumping warm and humid air into the Northeast and New England today, in true summer fashion. In fact, away from the shorelines, Monday will be a flat out hot and humid day. The National Weather Service has posted Heat Adversaries for much of the Northern Mid-Atlantic and southern half of the Northeast and New England.Here on the Cape, a strong southwest wind – which will increase to 15 to 25 mph with gusts to 35 mph at times – blowing off the water will help cap the warmth at more tolerable levels today…with midday and afternoon highs generally in the middle and upper 70s. Even so, the air will feel rather thick and uncomfortable as dew point values reach well into the 60s.
A cold front is dropping southward from Canada and will pass through New England later today and tonight, slipping offshore and south of the region Tuesday morning. Ahead of this frontal zone, clouds will be on the increase today and scattered showers and thunderstorms will fire off across New York State and New England. While the bulk of this activity is likely to remain to our north and west, a fizzling downpour and rumble of thunder can’t be ruled out of the forecast very late today and through the night tonight.
With the cold front still in the neighborhood first thing tomorrow morning, we’ll likely start our Tuesday a bit gray and humid with maybe a shower. However, the boundary will slip southward through the morning hours and the air will dry out and skies will clear out before midday…leading to a very pleasant second half of the day.
